The Lowdown

Righto, let's get into it. This is Karramarro we're lookin' at, a solid point break that needs a good NW swell to get goin'. It's a fickle one, "inconsistent" as they say, but when it lines up, it can be magic. The water is sittin' at a balmy 73.4°, which is 4.7° warmer than usual – that’s a proper anomaly, feels like a summer bath out there.

First up, Sunday the 13th is a bit of a tease. We've got 4.6ft of NW swell at 12 seconds, but that cross-on wind from the NNE at 6 mph is messin' with the face. Combined wave energy is moderate at 574, but the vibe is marginal – not worth paddlin' out for.

Now, Monday the 14th is where it starts to get interesting. The morning session is glassy with a 4.3ft NW swell at 12 seconds. That's clean as a whistle, even if the energy has dropped a bit to 423. It's a good opportunity to get some fun ones before the wind picks up. The afternoon drops off to 3.6ft, still glassy though, but just not as strong.

Tuesday the 15th and Wednesday the 16th are a write-off. The swell is small and the wind is all over the place. We're talkin' poor surf conditions across the board, just a bumpy mess. Best give it a miss.

Thursday the 17th is a 'maybe' – swell jumps to 5.6ft in the morning and 5.2ft in the arvo, both from the NW with 11-second periods. The energy is strong (676 and 595), but the cross/cross-on wind keeps it from being clean. Marginal.

Friday the 18th is another rest day. Small swell and messy conditions, nothin' to write home about.

Now, listen up, because this is the standout. Saturday the 19th of September. The morning is the pick of the entire forecast. We’ve got a clean 7.5ft of NW groundswell clockin' in at 14 seconds with glassy conditions and a light ESE breeze at 3 mph. The combined energy is a serious 1892, that's strong. This is an excellent session for experienced surfers – it'll be a bit much for the groms, but for the rest of us, it's the one to circle on the calendar. The arvo is still big at 6.9ft, but the wind swings onshore from the NNE, which makes it marginal.

Sunday the 20th is a drop-off. 4.6ft is still there but onshore wind makes for average, crowded conditions.

Then we get a beautiful run from Monday the 21st right through to Wednesday the 23rd. Monday morning and afternoon are both absolute pearlers: 6.2ft of NW swell at 13 seconds, glassy, clean. Energy is over 1200. You'll be gettin' some proper waves. Tuesday the 22nd is glassy all day too, with 5.2ft in the morning and 4.6ft in the arvo. Wednesday the 23rd morning has a bigger 6.6ft NNW swell at 13 seconds with clean, cross-off wind – energy at 1295, still very good. The arvo on Wednesday gets a bit crossed up again.

After that, from Thursday the 24th through to Saturday the 27th, it drops right off. The swell gets small and the wind is poor. There's a big gap of poor conditions.

Then on Sunday the 27th of September (more than a week away), we see a pulse of long-period swell. 4.9ft in the morning and 5.2ft in the arvo, both from the NW with a period of 14-15 seconds. The energy is strong, over 1000. But the wind is onshore and cross-onshore, making it marginal. This one is a promising but less certain long-range call – could be worth a look if the wind forecast cleans up, but right now it's a gamble.

Monday the 28th is similar, 5.2ft with onshore wind, still marginal.

So, for the real deal: get on Saturday the 19th of September morning for the biggest, cleanest swell of the period, and the Monday 21st through Wednesday 23rd for a solid run of fun, clean waves.

Stay stoked, catch ya in the water.

Information about the Karramarro Surf forecast

The above surf forecast table for Karramarro provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Karramarro can be found by selecting the local surf guide option on the grey menu. Our Karramarro surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Karramarro) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Karramarro may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
